viewtopic.php?f=13&t=18484 I sent intimate photos/video to my scammer or he says he recorded my activities on webcam, and now he is threatening to publish them. What can I do?
Unfortunately, there is not much you can do. The only advice we can give you is not to give in to blackmail demands, and once again, cut off ALL contact with the scammer. If he cannot reach you, he cannot blackmail you. If he knows that he has power over you, he will continue to abuse that power and demand more and more money. He may promise to destroy the photos/video, but remember he is a liar and a thief, and his promises are worth nothing.
The truth is, in most cases the scammer will not follow through with this threat, because following through will cost him time and money. If he tries to post anything pornographic, most public sites would delete it anyway. In the unlikely event that he does post something, you need to be proactive and contact the site immediately to have it removed. Depending on the threats, you may want to file a report with law enforcement.
Just remember for the future that any photo or video you give to ANYONE is out of your control, and anything you do on webcam can be recorded. This particular issue is not exclusive to scammers - the internet is full of stories of angry people who posted intimate details or photos/video of ex-partners after a relationship ended badly.
